Two experiments were conducted to determine whether water extracts from Artemisia capillaries (A. capillaries) and Camellia sinensis (C. sinensis) could be used as alternatives to antibiotic growth promoters in broiler feed. The experiment 1 was verified their chemical composition, extracts yields, total phenolic compounds concentration, antioxidant activity, antimicrobial activity, and chicken splenocytes proliferation through in vitro test. The extract yields of A. capillaries and C. sinensis were 26.5 and 16.8%, respectively. Total phenolic compounds concentrations of them expressed as gallic acid equivalent were 15.28 and 26.74 mg/mL, respectively. Electron donating abilities of them expressed as $SC_{50}$ showing 50% DPPH radical scavenging were 0.30 and 0.06 mg, respectively. Bacterial inhibitory rates of them against Escherichia coli, Staphylococcus aureus, and Salmonella Typhimurium were ranged from 42.1 to 52.3% and from 21.6 to 33.7%, respectively. And, these extracts increased proliferation of chicken splenocytes. Especially, A. capillaris was more excellent than Echinacea and Concanavalin A known as T-cell stimulator. The experiment 2 was investigated their effects on growth performance, relative organ weight, cecal microflora, blood biochemical parameters, and splenic cytokines mRNA expression in broiler chicks. Four hundred eighty 1-day-old male broiler chicks (Ross 308) were divided in to 4 treatment groups with 4 replicates of 30 birds in each group: NC (control, no antibiotics), PC (avilamycin, 10 ppm; salinomycin, 60 ppm), AC (A. capillaries, 100 ppm), and CS (C. sinensis, 100 ppm); treatments were administered through water supplementation. Final body weight was significantly higher in all treated groups than in NC (p<0.05). Cecal Salmonella numbers were significantly or somewhat decreased in all treated groups than in NC (p<0.05). The relative weights and lengths of the small intestine were more significantly decreased in the PC and AC groups than in the other groups. Cecal Salmonella numbers were significantly or somewhat decreased in all treated groups than in the NC group (p<0.05). The contents of total cholesterol, aspatate aminotransferase, and alanine aminotransferase in blood serum were more significantly decreased in all treated groups than in NC (p<0.05). In conclusion, these results suggested the possibility that these extracts could serve as alternatives for antibiotic growth promoters.

This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by $CCl_4$. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the $CCl_4$-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by $CCl_4$ treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by $CCl_4$ treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by $CCl_4$. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.

It has been reported that various kinds of chinese herbs have an activity of promote growth rate in both animals and human. To investigate the growth promoting effect of the selected plants, fish and pigs were used as experimental animals. In fish, Eleutherococcus senticosus extract and Artemisia capillasis extract were found to be most effective. And these plant extracts were given to pigs. The result showed that plant extracts-fed pigs were significantly increased their body weight gain at 7.06% of average daily gain, as compared to control. The verify this results, secreted growth hormone (GH)levels and insulin-like growth factor-1 (ICF-1) levels into blood were measured. This result indicated that GH and IGF-1 levels in the blood in plant extracts-fed pigs were higher that those of control. To confirm growth promotion effect on human, we manufactured the mixture of these plant extracts, and coated this mixture onto rice, named as $Kiwoomi^{TM}$. When we administered $Kiwoomi^{TM}$ to elementary students, it was found to be effective in growth promotion. This result showed that $Kiwoomi^{TM}$-treated elementary students significantly increased their growth rate (about 2.14 times), as compared to untreated children. Taken together, it is suggested that this functional rice ($Kiwoomi^{TM}$) might be helpful for growing children without any side effects.

This study was conducted to determine the effect of mugwort powder on meat composition and sensory characteristics in finishing gilts $(LY{\times}D)$. Twenty pigs (75kg) were randomly allotted to four treatments. Mugwort powder was added to final concentrations of 0(C), 0.5(T1), 1.0(T2), and 1.5%(T3) in the basal diet. Pigs were fed with the specified diet for 50 days. Carcass characteristics and cooking loss were not significantly affected by mugwort powder supplementation. The WHC and cooking loss of T2 and T3 were not significantly different than the control. However, the pH values for meat from gilts fed the T1 and T3 diets were significantly lower than the control (p<0.05). Shear force values of fresh meat were highest with the T3 diet (p<0.05), while the shear force values of cooked meat were significantly lower than the control with the T2 and T3 diets. Texture values of hardness, brittleness, gumminess, chewiness, and adhesiveness were significantly higher with the T3 diet (p<0.05), however values for cohesiveness and springiness were not significantly affected by mugwort powder supplementation. These results indicate that the feeding of mugwort powder improves the shear force of cooked meat from gilts fed the T3 diet, however the carcass, WHC and cooking loss characteristics in gilts are not affected by mugwort powder supplementation.
